When do I start reaching out to Agents, PM’s, and wholesalers?

[James H Webb III]

I'm looking to buy my third property! I bought a house hack, followed by a single family that I used a HELOC for the down payment. Now I am looking to buy a third property to BRRRR. My question pertains to marketing myself to agents, contractors, property managers, etc. I want to use my HELOC to fund the Rehab and purchase the home with hard money lending. My hesitancy is that I won't have the HELOC paid off for another 4-5 months. I want to start reaching out now but don't want to put a lot of work on the plates of professionals that I intend on working with until I know I can procure the deal quickly. I work in sales so I know what it's like to be brought work without pay and don't want to burn bridges or make team members think I am not serious because I am not prepared to move immediately. Any advice is greatly appreciated!
